I've had this unit installed for a month or so now and I love it. I bought the HD radio module and the bluetooth module along with it and it's awesome.
I have everything working beautifully EXCEPT for the rear view camera. And I don't get it. I have the Violet/White wire from the HU hooked up to the correct color (in my 07 Ford Five Hundred's case, green) wire on the PAC C2R-FRD1 factory wiring harness adapter according to the PAC install instructions. I've got the camera spliced into the backup light wire so that it only comes on when the backup lights come on (which only happens when put in reverse).
There are two things on the HU you have to set in order to use a rear view camera. In order for the HU to detect whether you are in reverse or forward it detects a change in polarity of the power is either Battery or Ground in the settings menu and then you have to tell the HU to "turn on" the camera function in the Source menu. You can't actually "turn on" the camera function if the camera polarity setting says Off. Makes sense but I'm just trying to make sure I've covered everything I know about the situation.
The problem I'm having is that when you start the car and the radio comes on, after a few seconds the screen goes black (only because the power to the camera is not on unless I'm in reverse) with the "Screen Image May Appear Reversed" warning at the top when I'm in anything other than reverse. Park, Forward, low gears and Neutral all do this.
The first thing I tried was changing the camera polarity setting from Battery to Ground. I even turned the car on and off between each setting change and re-tested. If I start the car with the camera polarity set to Battery then I can change the camera polarity setting to Ground and it does the same thing. If I set the camera polarity to Ground and restart the car then I can't get the HU to come off the rear view video screen at all. I have to reset the HU to get it to the point where I can see the screen again.
What the hell is going on? What am I missing? The only thing I can think of is that the installation manual for the HU shows a fuse resistor between the Violet/White HU wire and the factory wiring harness adapter wire which is not there. Of course, it doesn't tell you what kind to use but that is the only thing I can think of.
Any thoughts? Anyone have any experience with this?
Help would be greatly appreciated.
Thanks in advance.
